Sad

At first blush, a man being killed during S&M sounds kinda macabrely funny and/or another excuse for prudes to say that sex-is-dirty-especially-with-handcuffs-so-DON'T-DO-IT-KIDS
-or-you'll-DIE-and-go-to-HELL, but if you read the story, it's really very sad. He worked hard for his success and was killed for it. That's just wrong.
